The all-akustik group was founded in 1972 in Hannover by H.-D. Hoffmann, H. Pabel, H. Enders and F. Hofmann. From the beginning, Quadral was split in 2 divisions, i.e. industrial production and full acoustics.
Towards the end of the seventies, all-akustik made its own loudspeaker named Quadral. In just a few years, Quadral became the synonym for high quality loudspeakers.
Quadral launched various high end loudspeakers, such as the Titan, Vulkan, Montan and Wotan. Names that still have a magical sound in the ears of true music lovers.
Since 1998, chief developer Berndt Stark, has been setting new trends with Quadral. He promoted new techniques, such as the pressure chamber reflex principle. You certainly should not forget the Quadral ALTIMA© membrames and RiCom tweeters. His concepts won many awards and they were very well tested by various trade journals. Partly as a result of this, Quadral loudspeakers are synonymous to neutral sound, balance and richness in detail.
